Thatcham · TR19 Grease
We degrease the canopy, baffle filters and extractor fan for Thatcham restaurants, takeaways and pubs - so the system pulls properly, runs cooler and holds a current TR19 certificate.
Thatcham
Thatcham fries hard along the Broadway, Bath Road and Chapel Street, where pizza houses, kebab shops, Indian restaurants and cafes run their extraction flat out through every service.
The settings vary, the grease does not. Across Bath Road, Henwick and the suburban strips, the takeaways and grill houses run the single hardest test an extraction canopy faces. Thatcham rates hundreds of food premises, most of them frying in a tight footprint.
We degrease the part of the system the Bath Road and Henwick cooks work under - the canopy, the baffle filters and the extractor fan. Done properly it pulls the way it was designed to, clearing heat and steam, holding a current TR19 Grease certificate, and running cooler, because a clean Thatcham fan is not fighting a greased one to move the same air.
The system
Extraction cleaning is the accessible heart of the system - the kit above a hard-frying Bath Road cookline that does the work and shows the grease first.
Canopy inside and out, baffle filters cleaned or replaced, and the extractor fan and housing degreased - that last part loses performance quietly as grease builds on the blades through a hard Henwick service. The work meets the TR19 Grease standard, with before-and-after evidence and a certificate, so the system pulls properly and your Thatcham fire risk assessment and insurer have the paperwork they ask for.
Filters
The standard for commercial cooklines: they trap grease and slow flame spread. Cleaned, or replaced when warped or corroded.
Common on older or lighter setups; they clog fast and pass grease through if neglected. We flag where a baffle upgrade is overdue.
On the odour and emission-controlled systems near Thatcham's residential streets; cleaned or changed so the downstream stages are not overwhelmed.
Fire
A Thatcham cookline's extraction and its fire protection are one system - and a clean is the moment to check the join.
Nozzles aimed at the canopy and cooking points; grease build-up around them on a busy Bath Road line is exactly what they exist to fight. We clean around them without disturbing the system.
Where the gas shuts off if extraction fails on a Bath Road line, we work without tripping it - and flag it if it is not behaving.
Checked for the grease that would stop them closing - a quiet failure point on a Henwick system that a quick canopy wipe misses.
On the ground in Thatcham
We are under Thatcham's canopies every week. Real jobs, not stock shots.
The plenum and filters at a local pub in Thatcham were caked in baked-on grease, well past a safe level over the cook line. We cleaned the canopy, filters and plenum back to metal, degreased the fan housing and refitted the cleaned filters. The system was cleaned to TR19 and the fan pulled freely again, with full documentation for their records. We set up a recurring three-monthly clean to keep on top of it.
Why it pays
Extraction cleaning is a fire-risk job first - but it pays back every Thatcham service.
With the canopy and fan clean, heat and steam clear off a hard Bath Road cookline faster, the kitchen runs cooler, and the fan works less to move the same air. Leave it greased and you have a fire risk, a failed inspection point and an uncomfortable kitchen together. Frequency follows the cooking load - the Henwick takeaways need it more often than a daytime cafe - and the certificate sets the next date.
Inspect the Thatcham canopy, filters and fan, agree scope and frequency.
Remove filters and access panels, protect the cookline.

Questions
It depends how hard the kitchen runs. Under TR19 Grease, heavy use of 12 to 16 hours a day points to roughly every three months, moderate to every six, light to every twelve. A busy Bath Road or Henwick kitchen sits in a tighter band than a daytime cafe.
Extraction cleaning covers the canopy, filters and fan; where the concealed duct run behind them is also loaded - as it often is in a tight Bath Road kitchen - we clean the full run to TR19 and certify it together.
Yes. Most venues we clean around Bath Road and Henwick are busy through the evening, so we work overnight, early mornings or on closing days, at no extra charge for out-of-hours work.
Yes. The takeaways and grill houses around Henwick and Chapel Street run a canopy, filters and a fan and often carry a heavy grease load for their size. We clean and certify them the same way as a full restaurant system.
It can. An inspection covers the physical condition of the premises, ventilation included, so a grease-laden canopy or fan over a Broadway cookline can count against your score.
Every clean finishes with a dated TR19 certificate, before-and-after photographs and a condition report - the evidence a Bath Road operator's insurer or fire risk assessor expects to see.
Yes. Where a filter is warped, corroded or a mesh type that keeps passing grease, we say so and swap it - common on the older Henwick takeaway canopies that have run hot for years.
Local knowledge
People have cooked beside the Thatcham reedbeds for some ten thousand years - the Mesolithic hunter-gatherers whose hearths by the Kennet make the town the strongest claimant to being the oldest continuously inhabited place in Britain. The cooking fires have long since moved indoors, but the town's kitchens still coat their canopies and extract systems in grease every service. Left in place it feeds flame and starves airflow, so we strip, degrease and certify extraction from the filter to the fan to the TR19 grease standard.
